I am building 2 of the 12 inch Deathboxes (DB212?), one for my car and one for the mrs car. I need opinions on the drivers for each. My car already has a 4 channel amp which can be bridged down to 2 channels at 380watts RMS each Channel. So looking for something that is DVC, with each coil able to be independantly powered by a different amp, and around 700-800RMS. Looking for super low, super loud and good SQ bass, so high XMAX etc. For the Mrs car she has a 2 channel bridged amp good for 500RMS, so looking for same attributes as the sub for my box but less RMS value. All opnions welcome.
